摘要

研究了数字超模分布布拉格光栅(DS-DBR)激光器中的1/f噪声。对老化前后各部分，包括主动部分和调谐部分的电压噪声谱密度进行了表征。结果表明，老化提高了有源区pn结缺陷的噪声水平和无源区饱和噪声水平。

1/f Noise Characterization for Wavelength-tunable Semiconductor Lasers

The 1/f noise in a digital super-mode distribute Bragg grating (DS-DBR) lasers is investigated. The voltage noise spectral density of each sections, including the active and the tuning sections are characterized before and after aging. The results indicate that aging increases the noise level from pn junction defects in the active region and the saturation noise level in the passive sections.
